No

=>Go to Inspection for open circuit in vehicle speed sensor power supply circuit.

4. Inspection for open circuit in vehicle speed sensor power supply circuit

1) Turn OFF the ignition switch.

2) Disconnect the vehicle speed sensor harness connector (E37).

3) Connect a test lamp between the ignition power supply circuit (pin 1 of E30) and the body ground.

Refer to "LHD Engine Control (4JJ3 without DPD)" in the ETM (wiring diagram). (Open using the ETM viewer.).

Refer to "RHD Engine Control (4JJ3 without DPD)" in the ETM (wiring diagram). (Open using the ETM viewer.).

4) Turn ON the ignition switch. Does the test lamp illuminate?

Yes

=>Go to Vehicle speed sensor signal voltage check.

No

Repair the open circuit or high resistance in the ignition power supply circuit between the METER(IG1) 5A fuse and the vehicle speed sensor (pin 1 of E37). Inspect the METER(IG1) 5A fuse first.

=>Go to Repair verification.

5. Vehicle speed sensor signal voltage check

1) Observe the Vehicle Speed parameter on the scan tool while intermittently connecting and disconnecting a test lamp between the vehicle speed sensor signal circuit (pin 3 of E37) and the battery power supply. Does the Vehicle Speed parameter change when a test lamp is disconnected?

Refer to "LHD Engine Control (4JJ3 without DPD)" in the ETM (wiring diagram). (Open using the ETM viewer.).

Refer to "RHD Engine Control (4JJ3 without DPD)" in the ETM (wiring diagram). (Open using the ETM viewer.).

Yes

=>Go to Inspection for open circuit in vehicle speed sensor ground circuit.

No

=>Go to Inspection for open circuit and short circuit in vehicle speed sensor signal circuit.

6. Inspection for open circuit in vehicle speed sensor ground circuit

1) Turn OFF the ignition switch.

2) Connect a test lamp between the ignition power supply circuit and the ground circuit (pins 1 and 2 of E30).

Refer to "LHD Engine Control (4JJ3 without DPD)" in the ETM (wiring diagram). (Open using the ETM viewer.).

Refer to "RHD Engine Control (4JJ3 without DPD)" in the ETM (wiring diagram). (Open using the ETM viewer.).

3) Turn ON the ignition switch. Does the test lamp illuminate?

Yes

=>Go to Vehicle speed sensor harness connector inspection.

No

Repair the open circuit or high resistance in the ground circuit between the vehicle speed sensor (pin 2 of E37) and the body ground.

7. Inspection for open circuit and short circuit in vehicle speed sensor signal circuit

1) Inspect the signal circuit between the ECM (pin 22 of C8) and the vehicle speed sensor (pin 3 of E37) for the following. Is the result normal?

Refer to "LHD Engine Control (4JJ3 without DPD)" in the ETM (wiring diagram). (Open using the ETM viewer.).

Refer to "RHD Engine Control (4JJ3 without DPD)" in the ETM (wiring diagram). (Open using the ETM viewer.).

Yes

=>Go to ECM harness connector inspection.

No

Repair the circuit as necessary.

=>Go to Repair verification.

8. Vehicle speed sensor harness connector inspection

1) Inspect for poor connections at the vehicle speed sensor harness connector (pins 1, 2, and 3 of E37). Is the connection status normal?

Refer to "LHD Engine Control (4JJ3 without DPD)" in the ETM (wiring diagram). (Open using the ETM viewer.).

Refer to "RHD Engine Control (4JJ3 without DPD)" in the ETM (wiring diagram). (Open using the ETM viewer.).

Yes

=>Go to VSS components inspection.

No

Repair the connections as necessary.

=>Go to Repair verification.

9. VSS components inspection

1) Inspect the vehicle speed sensor, drive gear, driven gear, and output shaft for the following. Is the result normal?

Yes

Replace the vehicle speed sensor.

Refer to "5.Transmission, Transaxle 5Z.Transmission Electrical Control(MVL) vehicle speed sensor removal".

Refer to "5.Transmission, Transaxle 5Z.Transmission Electrical Control(MVL) vehicle speed sensor installation".
